The power control method is applied to electronic equipment and comprises the following steps: acquiring an uplink power level configured by a network terminal; determining an adjusted uplink power based on the network transmission condition determined by the electronic device, wherein the adjusted uplink power is within the power range determined by the uplink power class and is different from a nominal power of the uplink power class; and transmitting an uplink signal using the adjusted uplink power.
Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a power control method and electronic equipment.
Background
The uplink power of the electronic device is the power used by the electronic device to transmit signals. Generally, the uplink power is limited to a maximum value due to factors such as the emission capability of the rf device of the electronic device and the mutual radiation interference in the mobile network environment. This maximum value will generally be related to the following parameters:
1. the maximum uplink power of the electronic device configured by the network side, for example, a p-Max parameter configured in a system message 1 of a long term evolution LTE system; P-NR parameter in system message 1 of the new air-interface NR system. The maximum uplink power configured by the network end is used for ensuring that the electronic equipment can effectively send signals on one hand, and is used for reducing uplink interference among different electronic equipment on the other hand;
2. the radio frequency RF device (PA) of an electronic device has maximum power (capability) in steady state. If the actual power of the electronic device exceeds this maximum capability, the RF device may have problems of unstable device output power, accelerated aging, large increase in power consumption, and the like.
The final maximum uplink power may be a union of the two parameters, that is, a minimum value of the two parameters is taken as a maximum value of the uplink power that can be achieved by the electronic device.
In the prior art, each network-side configured power level corresponds to a default power, and the electronic device can only transmit uplink signals by using the default power. In this case, the electronic device lacks flexibility and cannot adjust the transmission power according to the network transmission condition or the power of the electronic device itself.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
[ NETWORK SYSTEM ]
As shown in fig. 1, in a network system, electronic devices 111, 112 are connected to a base station 120 through radio frequency links. The direction in which signals are transmitted from base station 120 to electronic devices 111 and 112 is the downlink direction, and the direction in which signals are transmitted from electronic devices 111 and 112 to base station 120 is the uplink direction. The base station 120 is connected to switches 130, 140 in the communication backbone and to an external network 150, such as the internet, via the switches 130, 140.
As shown in fig. 1, in the uplink direction, there is an uplink from electronic device 111 to base station 120 and an uplink from electronic device 112 to base station 120. If signals are transmitted simultaneously in both uplinks, interference may exist between the two uplinks. For example, to avoid excessive interference, the network side may send control information to the electronic devices 111 and 112 through the base station to control the power level of each electronic device. The control information is, for example, a p-Max parameter configured in system message 1 of the LTE system; P-NR parameters in system message 1 of the new air interface NR system, and the like.
As shown in fig. 1, electronic device 111 is farther from base station 120 than electronic device 112. Therefore, the network can set a higher power level for the electronic device 111.
Due to differences in rf devices of different electronic devices, the base station can tolerate a certain range of deviation for each power level, e.g., +2/-3dBm, i.e., one power range for each power level, and the network side can allow uplink signals within the power range.
In a mobile communication network, in a normal case, the maximum uplink power P-MAX configured for an electronic device is 23 dBm. However, currently, many electronic devices are high power user equipment HPUE, the maximum transmit power of the radio frequency RF components of which can reach 26dBm power (HPUE, PC 2). Therefore, the maximum emission power of such electronic devices with 3dBm is limited by the network side.
The inventor finds that in a weak environment, problems of high time delay, instable internet surfing, internet surfing failure, call failure or unclear call and the like of games can occur. This may be due to poor uplink signal quality of the electronic device. In this case, for example, retransmission of many packets may occur in the uplink. Such an improvement can be achieved by increasing the uplink power of the electronic device. However, the configuration of the network limits the performance of the electronic device.
After the electronic device receives the power level configured by the network, the electronic device performs transmission of the uplink signal by using a default uplink power or a nominal power corresponding to the power level. Typically, the nominal power is the power at the middle of the power range for the corresponding power level.
On the other hand, if the electronic device transmits the uplink signal at high power, it consumes power of the electronic device, reducing the usage time of the electronic device, and in addition, it may have an influence on the battery life of the electronic device.
[ method examples ]
Fig. 2 shows a schematic flow diagram of a power control method according to an embodiment.
As shown in fig. 2, in step S12, the uplink power level configured by the network is obtained. For example, the p-Max parameter may be configured in system message 1 of the long term evolution LTE system; and configuring the uplink power level of the electronic equipment by using the P-NR parameter and the like in the system message 1 of the new air interface NR system.
At step S14, an adjusted uplink power is determined according to the determined network transmission condition by the electronic device, wherein the adjusted uplink power is within the determined power range of the uplink power level and is different from the nominal power of the uplink power level. The network transmission status may be, for example, a signal strength of a current network, or a status of the electronic device that uses the network for transmission currently, or the like. The nominal power is a standard power value of a corresponding power level, for example, a standard power value corresponding to a power level 2(PC2) in mobile communication is 26dBm, an allowable error range of the PC2 is + -2dBm, and thus, a power range corresponding to the PC2 is 24-28 dBm. In a general case, the uplink power (i.e., nominal power) determined by the electronic device should be 26 dBm. Here, the adjusted uplink power may be a value greater than 26dBm or a value less than 26dBm according to the network transmission condition, so as to preferentially satisfy the transmission performance requirement and/or the handset power consumption requirement according to different situations.
At step S16, an uplink signal is transmitted using the adjusted uplink power.
By the method, on one hand, the adjusted uplink power meets the requirement of the uplink power level configured by the network end, and therefore, the current mobile network cannot be greatly influenced. On the other hand, by adjusting the uplink power, the communication quality of the electronic device may be improved and/or the power of the electronic device may be saved. By means of the solution herein, a flexible way can be provided to enable a better balance between improving the uplink communication quality and improving the performance of the electronic device by adjusting the uplink power while minimizing the impact on the mobile network.
In a first embodiment, the adjusted uplink power may be increased stepwise from the nominal power by a predetermined adjustment magnitude below the upper limit of the power range if the network transmission conditions meet a first predetermined condition. The designer of the electronic device may set the first predetermined condition as needed, for example, the signal strength detected by the electronic device is less than a predetermined value, and the like. For example, the predetermined adjustment magnitude may be 0.1dBm, or other predetermined value. In many cases, it is difficult to determine the magnitude of power that needs to be increased. Here, only the adjustment purpose to be achieved needs to be set, and the uplink power in the electronic device can automatically approach the target value, so that the effect of automatic adjustment is achieved, and a complex calculation process can be omitted.
The adjusted uplink power may be an increased uplink power relative to the nominal power. The uplink power may be gradually increased in the above step-by-step manner, or the uplink power value may be calculated by the calculating unit in the electronic device based on the network transmission condition. Transmitting an uplink signal using the increased uplink power if the network transmission condition satisfies a first predetermined condition.
With the development of the technology, the implementation mode of the electronic equipment is more and more flexible. The above-described processing may be realized by dedicated hardware, or may be realized by a processor such as a central processing unit or the like in a software execution manner. The processing result is then transferred by an electrical signal to the radio frequency antenna element as transmitter. The electrical signal comprises a data signal to be transmitted and the uplink power required for transmission. And the radio frequency antenna unit amplifies the data signal according to the set uplink power and sends the data signal to a corresponding base station through an antenna.
The electronic device can utilize the existing parameters in the mobile communication system to judge the network transmission condition and/or set the first predetermined condition, thereby saving the additional processing of the electronic device and reducing the additional overhead generated by the electronic device for realizing the scheme. For example, the first predetermined condition includes at least one of the following conditions:
-the uplink retransmission rate of the physical layer (layer 1 or L1) channel is above a pre-set retransmission rate threshold value. This indicates that the base station does not normally receive the data packet transmitted by the electronic device, and therefore, the wireless connection between the electronic device and the base station can be strengthened by increasing the uplink power. For example, one example value of the retransmission rate threshold is 60%.
The uplink power level configured by the network end is the highest uplink power level and the duration of the uplink power level exceeds a preset first time threshold value. This indicates that the network side determines: the connection quality with the electronic device is poor and attempts have been made to instruct the electronic device to transmit signals at the highest uplink power to strengthen the wireless connection.
-the maximum transmission power of the radio frequency device of the electronic equipment is greater than or equal to said adjusted uplink power.
-the duration of time the electronic device is in a state in which the screen is lit exceeds a second time threshold value. This indicates that the current user is always using the electronic device, and therefore, in this case, the uplink power is increased, so that the network transmission performance is improved, and better user experience can be provided for the user.
-the electronic device detecting that the duration of the continuous operation of the user exceeds a third time threshold value. Similar to the reason described above, in this case, the uplink power is increased, so that the network transmission performance is improved, and a better use experience can be provided for the user.
-the duration that the uplink of the electronic device is in the persistent transmission state exceeds a fourth time threshold value. This is also similar to the case described above. In this case, the uplink power is increased, so that the network transmission performance is improved, and better use experience can be provided for users.
-the running application in the electronic device requires an uplink delay below the first predetermined delay and/or an uplink throughput above the first predetermined throughput. For example, users are using electronic devices for gaming, voice calls, uploading data, and the like. In this case, the uplink power is increased, so that the network transmission performance is improved, and better use experience can be provided for users.
The first to fourth time threshold values, the first predetermined time delay and the second predetermined time delay described above may be empirical values. The designer of the electronic device may set the above values based on the counted use of the electronic device by the user. For example, the first time threshold value may be 1 minute, the second through fourth time threshold values may be 5 minutes (they may also be different values), respectively, the first predetermined time delay is 1 millisecond, and the first predetermined throughput is 1 Mbits/s.
In addition, the network transmission performance and the battery power requirement of the electronic equipment can be considered.
For example, when the electronic device is determined to be in a strong signal environment and the power of the electronic device is greater than a first power threshold value according to the network transmission condition, the uplink signal is transmitted by using the increased uplink power. When the reference signal received power RSRP received by the electronic device is greater than-113 dBm, the electronic device determines that the network transmission condition is in a strong signal environment, and the first power threshold may be 70% of a battery power of the electronic device.
For example, when the electronic device is determined to be in a weak signal environment and the power of the electronic device is greater than a second power threshold value according to the network transmission condition, the uplink signal is transmitted by using the increased uplink power. When the reference signal received power RSRP received by the electronic device is less than or equal to-113 dBm, the electronic device determines that the network transmission condition is in a weak signal environment, and the second power threshold may be 30% of a battery power of the electronic device.
Here, the strong signal environment is relative to the weak signal environment. The signal strength in a strong signal environment is greater than the signal strength in a weak signal environment. Although here, as an example, a boundary of-113 dBm is used to distinguish between a strong signal environment and a weak signal environment, it should be understood by those skilled in the art that, on the premise that the signal strength in the strong signal environment is greater than that in the weak signal environment, the designer may define the strong signal environment and the weak signal environment as required, for example, RSRP in the strong signal environment is greater than-110 dBm, and RSRP in the weak signal environment is less than or equal to-113 dBm.
Here, the second power threshold value is less than the first power gate limit. This is because, in a weak signal environment, the user demands more for transmission performance.
The electronic device may also revert from the state of increased uplink power described above to a state of nominal power. For example, the electronic device exits the state described above when at least one of the following conditions is satisfied:
-the network configured uplink power level is a lower uplink power level lower than the highest uplink power level and the duration at said lower uplink power level exceeds a predetermined time. In this case, the electronic device enters a network coverage area with better signal, and therefore, no further increase of the uplink power is needed.
-in weak signal environments, the battery level of the electronic device is less than 30%. In this case, in order to ensure the standby time of the electronic device, the uplink power is reduced to save power.
-in a strong signal environment, the battery level of the electronic device is less than 70%. In this case, the uplink power is appropriately reduced without significantly affecting the communication of the user, and the standby time of the electronic device can be extended.
After increasing the uplink power, the communication quality of the electronic device does not improve or there is a situation where no increase of the uplink power is needed. For example, due to an abnormality of an operator or a server, the upper layer software of the electronic device detects that a user usage scenario is not improved, for example, a game delay is still high or a voice packet loss rate of an IP call is still high. For example, the electronic device enters an off-screen state, or the user exits the more demanding application software.
In another embodiment, the adjusted uplink power is gradually decreased by a predetermined adjustment amount in case the network transmission condition satisfies a second predetermined condition. The designer of the electronic device may set the second predetermined condition as needed, for example, the signal strength detected by the electronic device is greater than a predetermined value, and the like. For example, the predetermined adjustment magnitude may be 0.1dBm, or other predetermined value. By reducing the uplink power if the second predetermined condition is satisfied, the power consumed by the electronic device can be reduced if the transmission performance requirement is satisfied. Therefore, the service life of the electronic equipment after each charging can be prolonged, and the service life of the battery can also be prolonged. Furthermore, similar to the above description regarding increased uplink power, such a step adjustment manner can achieve the effect of automatic adjustment, and can omit a complicated calculation process.
The adjusted uplink power may be an uplink power that is reduced relative to the nominal power. The uplink power may be gradually reduced in a step-by-step manner, or an uplink power value calculated by a calculation unit in the electronic device based on the network transmission condition. Transmitting an uplink signal using the increased uplink power if the network transmission condition satisfies a second predetermined condition.
The electronic device can utilize the existing parameters in the mobile communication system to judge the network transmission condition and/or set the second predetermined condition, thereby saving the additional processing of the electronic device and reducing the additional overhead generated by the electronic device for realizing the scheme. For example, the second predetermined condition includes at least one of the following conditions:
-the uplink power level configured by the network end is a lower uplink power level lower than the highest uplink power level and the duration at the lower uplink power level exceeds a preset fifth time threshold value. The lower uplink power level may be the lowest uplink power level. This indicates that the current network conditions are better and that lower uplink power can also meet the communication requirements. In this case, the uplink power is properly reduced without much influence on the transmission, but this can save the power of the electronic device, thereby extending the battery life and the battery life.
-the electronic device is in a state where the screen is off exceeding a sixth time threshold value. This indicates that the user is not using the electronic device for a while. In this case, the user's use is not affected by only ensuring the lowest connection requirement. In this case, the power of the electronic device can be saved by appropriately reducing the uplink power, thereby prolonging the battery life and the battery life.
-the electronic device is capable of allowing an uplink delay above the second predetermined delay and/or an uplink throughput below the second predetermined throughput. For example, a user sends a text message using an electronic device. In this application scenario, the transmission performance degradation caused by properly reducing the uplink power does not affect the use of the user. Also, this approach may conserve power of the electronic device, thereby extending battery life and longevity.
In addition, the timing of using the reduced uplink power may also be determined in consideration of the power and signal environment.
For example, when the electronic device is determined to be in a strong signal environment and the power of the electronic device is less than a third power threshold according to the network transmission condition, the uplink signal is transmitted with reduced uplink power. For example, when the reference signal received power RSRP received by the electronic device is greater than-113 dBm, the electronic device determines that the network transmission condition is in a strong signal environment, and the third power threshold is 70% of the battery power of the electronic device.
For example, when the electronic device is determined to be in a weak signal environment and the power of the electronic device is less than a fourth power threshold value according to the network transmission condition, the uplink signal is transmitted with reduced uplink power. For example, when the reference signal received power RSRP received by the electronic device is less than or equal to-113 dBm, the electronic device determines that the network transmission condition is in a weak signal environment, and the second power threshold is 30% of the battery power of the electronic device.
[ electronic device embodiment ]
Fig. 3 shows a schematic block diagram of an electronic device. As shown in fig. 3, the electronic device 30 includes: an obtaining device 32, configured to obtain an uplink power level configured by a network; determining means 34 for determining an adjusted uplink power based on the network transmission condition determined by the electronic device, wherein the adjusted uplink power is within a power range determined by the uplink power level and is different from a nominal power of the uplink power level; and a transmitting means 36 for transmitting the uplink signal using the adjusted uplink power.
The determining means 32 is adapted to increase the adjusted uplink power step by step from the nominal power by a predetermined adjustment magnitude below the upper limit of the power range if the network transmission conditions fulfil the first predetermined condition.
The adjusted uplink power is an increased uplink power relative to the nominal power. The transmitting means 36 is arranged to transmit the uplink signal rate using the increased uplink power if the network transmission conditions meet a first predetermined condition.
The first predetermined condition includes at least one of the following conditions:
-the uplink retransmission rate of the physical layer channel is higher than a preset retransmission rate threshold value;
-the uplink power level configured by the network end is the highest uplink power level and the duration at the highest uplink power level exceeds a preset first time threshold value;
-the maximum transmission power of the radio frequency device of the electronic equipment is greater than or equal to the adjusted uplink power;
-the electronic device is in a screen-on state exceeding a second time threshold value;
-the electronic device detects that the continuous operation time of the user exceeds a third time threshold value;
-the time that the uplink of the electronic device is in a continuous transmission state exceeds a fourth time threshold value;
-the running application in the electronic device requires an uplink delay below the first predetermined delay and/or an uplink throughput above the first predetermined throughput.
The emitting device 36 may be used to: when the electronic equipment is determined to be in a strong signal environment and the electric quantity of the electronic equipment is larger than a first electric quantity threshold value according to the network transmission condition, transmitting an uplink signal by increased uplink power; or when the electronic equipment is determined to be in a weak signal environment according to the network transmission condition and the electric quantity of the electronic equipment is larger than a second electric quantity threshold value, the uplink signal is transmitted with increased uplink power. When the reference signal received power RSRP received by the electronic device is greater than-113 dBm, the electronic device determines that the network transmission condition is in a strong signal environment and that the first power threshold is 70% of the battery power of the electronic device. When the reference signal received power RSRP received by the electronic device is less than or equal to-113 dBm, the electronic device determines that the network transmission condition is in a weak signal environment and the second power threshold is 30% of the battery power of the electronic device.
